Description
Technical Field
The present invention relates to an embroidery condition confirming system (system), apparatus and method for confirming an embroidery condition of an embroidery pattern selected and sewn by a sewing machine (sewing machine).
Background
In the related art, embroidery machines are provided with pattern data (data) for embroidery and perform embroidery based on the pattern data. When the pattern is composed of a plurality of lines, the user (user) performs replacement of the lines in accordance with the pattern as required.
If the sewing machine starts embroidering, the user automatically embroiders without a special operation until the next thread replacement. In some cases, for example, when the embroidered pattern is large, it may take thirty minutes or more until the next thread replacement. Therefore, the user presumes the timing at which the sewing machine may stop next time, and returns to the sewing machine at that timing, and the like.
On the other hand, when a thread break occurs in embroidery, the embroidery is interrupted halfway. If the user does not notice the interruption of the embroidery, it may result in that the embroidery is not performed and the sewing machine is left alone. If the setting time is long, it takes an excessive time until the embroidery is completed. Therefore, the user returns to the sewing machine from time to confirm whether the embroidery is normally performed.
Even if the user is at a place far from the sewing machine, if the condition of the sewing machine can be monitored (monitoring), the confirmation of the embroidery condition of the sewing machine can be performed. Therefore, there is the following method: a small-sized charge-coupled device (CCD) camera is installed inside a sewing machine, and an image that the sewing machine is embroidering is confirmed by a monitor (monitor) connected by a wire (see, for example, patent document 1).
[ background Art document ]

[ patent document 1] Japanese patent application laid-open No. Hei 5-64694
However, when the sewing machine and the monitor are connected by wire, a limit is generated in the moving range of the user. Therefore, it is also considered that wireless communication is performed between the sewing machine and a Personal Digital Assistant (PDA) without using a wire. However, if wireless communication using general data communication is used, an error (error) is detected when the communication is interrupted, and thus, the connection is cut off. In this case, the communication must be started again by manual work of the user.
In addition, when an image being embroidered is transmitted to a Personal Computer (PC) or a personal digital assistant (pda) via wireless communication, the data volume of the image becomes very large. Therefore, the hardware (hardware) of the sewing machine is overloaded, and a separate Central Processing Unit (CPU) or the like must be provided to process the image data.
Further, there is a concern that: the video data is transmitted while occupying a wireless communication line, thereby affecting other wireless communications. In addition, there are also problems as follows: when the personal digital assistant is far from the sewing machine to deteriorate the communication condition, the image is disturbed and then the animation is stopped. Even if the communication condition is recovered, the image is disturbed and the visibility is low.

In order to achieve the above object, the present invention is an embroidery status confirmation apparatus for confirming an embroidery status of an embroidery pattern selected and sewn by a sewing machine, comprising: an embroidery data receiving unit that receives embroidery data of the embroidery pattern that the sewing machine is performing sewing; a conversion part converting the received embroidery data into a unique code (unique); a status data receiving part receiving a unique code converted based on embroidery data that the sewing machine is performing sewing; and a code comparing section that compares the code converted by the converting section with the code received by the status data receiving section; the embroidery data receiving unit receives data in a transmission protocol (protocol) for accurately transmitting data to a transmission target, and the status data receiving unit receives data in a transmission protocol for transmitting data to a transmission target in a short time.
The embroidery situation confirmation apparatus of the present invention may further include an embroidery data request unit that requests the sewing machine for embroidery data currently performing sewing when the code comparison unit determines that the two codes do not match.
The embroidery state confirmation device of the present invention may further include a drawing unit that draws the embroidery state of the sewing machine based on the embroidery data stored in the storage unit and the number of needles after the start of sewing, when the state data receiving unit receives the state data including the unique code converted based on the embroidery data on which the sewing machine is executing and the number of needles after the start of sewing, and the code comparing unit determines that the two codes match.
As the unique code converted based on the embroidery data, a Cyclic Redundancy Check (CRC) code may be used.
The drawing unit may further include a drawing speed determination unit that stores the number of needles included in the status data each time status data is received, and determines the drawing speed based on a difference between the number of needles and a reception interval of the status data.
The embroidery state confirmation device of the present invention may further include a state data requesting unit that requests the sewing machine for the state data at predetermined intervals even if the state data receiving unit or the embroidery data receiving unit does not receive the data.
In addition, an embroidery situation confirmation system and an embroidery situation confirmation method provided with the embroidery situation confirmation device are also an embodiment of the present invention.
The present invention provides an embroidery condition confirmation system, including: a sewing machine for embroidering and an embroidering state confirming device for confirming the embroidering state of the sewing machine; wherein the embroidery condition confirmation apparatus comprises: an embroidery data receiving unit for receiving embroidery data of an embroidery pattern selected and sewn by the sewing machine; a conversion section that converts into a unique code based on the received embroidery data; a status data receiving part receiving a unique code converted based on embroidery data in which the sewing machine is embroidering; and a code comparing section that compares the code converted by the converting section with the code received by the status data receiving section; wherein the embroidery data receiving unit receives the embroidery data in a transmission protocol for accurately transmitting the embroidery data to a transmission target; the status data receiving unit receives the status data in a transmission protocol for transmitting data to the transmission target in a short time.

[ Effect of the invention ]
According to the present invention, the progress of embroidery with a sewing machine can be monitored in real time at a place remote from the sewing machine.
Further, since the embroidery state checking device is excellent in portability (portability), it is possible to monitor the progress of embroidery in different rooms or while moving without monitoring at a fixed place. In a communication method between a sewing machine and an embroidery condition confirmation device, in order to prevent a communication error (error), a communication method different from that when monitoring the progress condition of embroidery is used when embroidery data is transmitted. This makes it possible to transmit embroidery data reliably and transmit data for monitoring the progress state in a small amount of capacity.
In addition, the count value of the number of stitches and the drawing of the stitch (stich) are not updated while the radio wave does not arrive from the sewing machine to the embroidery condition checking device. On the other hand, when the radio wave condition is again improved and communication is resumed, the current embroidery condition can be displayed immediately and accurately.

(4) Embroidery data responding to the request of the embroidery data from the sewing machine 2 to the embroidery condition confirmation apparatus 3.
In the embroidery status confirmation system 1 of the present embodiment, the request signals or data of (1) to (4) are transmitted and received between the sewing machine 2 and the embroidery status confirmation device 3. At this time, the status data of (2) and the embroidery data of (4) are transmitted and received by different communication protocols (protocols). That is, the status data of (2) is transmitted in a transmission protocol capable of transmitting data to a transmission target in a short time. The embroidery data in (4) is transmitted in a transmission protocol that enables accurate transmission of data to a transmission target. In the present embodiment, the following example is explained: and (2) receiving and transmitting the state data of the (2) by using a User Datagram Protocol (UDP) communication protocol, and receiving and transmitting the embroidery data of the (4) by using a Transmission Control Protocol (TCP) communication protocol.
[1-2. Sewing machines ]
The sewing machine 2 is a sewing machine that can perform embroidery by performing sewing based on embroidery data input by a user, and is connected to the embroidery situation confirmation apparatus 3 via the wireless network N. As shown in fig. 2, the sewing machine 2 includes an input unit 4, a display unit 5, an embroidery data selection unit 6, a storage unit 7, an external storage unit 8, a temporary storage unit 9, a Cyclic Redundancy Check (CRC) data conversion unit 10, a status information creation unit 11, a needle count counting unit 14, a command (command) reception unit 15, a command determination unit 16, a TCP transmission unit 17, and a UDP transmission unit 18.
The input section 4 is a unit for inputting settings such as a user input operation request to the sewing machine 2 or setting of embroidery data. The input unit 4 is an input device represented by a mouse (mouse), a touch screen (including a touch screen provided in the display unit 5), or a keyboard (keyboard), for example.
The display unit 5 is a unit for displaying a screen for allowing the user to confirm, for example, the operation content or embroidery data of the sewing machine 2. For the Display unit 5, a Display (Display) device such as a Liquid Crystal Display (LCD) or a Cathode Ray Tube (CRT) may be used. The display unit 5 displays a pattern to be a candidate when embroidering is performed.
The embroidery data selection unit 6 selects embroidery data corresponding to the embroidery pattern selected by the user. The embroidery data selection unit 6 is configured to refer to the contents of the storage unit 7 and the external storage unit 8 inside the sewing machine 2. The storage unit 7 is a Read-Only Memory (ROM), and a Non-volatile Memory (Memory) can be used. The storage unit 7 stores embroidery data. The external storage unit 8 is a storage unit having a storage area in a Universal Serial Bus (USB) or the like, and stores embroidery data in the storage area.
The embroidery data stored in the storage unit 7 or the external storage unit 8 is data necessary for the sewing machine 2 to perform embroidery, and includes pattern information for performing embroidery, size (size) information of the pattern, information of the number of stitches necessary for completing the pattern, information of the color used, and information of timing for replacing the thread. The embroidery data is data of a size of about several hundred kilobytes (kilobyte).
When the user selects a pattern to be embroidered, the embroidery data selection unit 6 displays the pattern based on the embroidery data stored in the storage unit 7 or the external storage unit 8 on the display unit 5. The user operates the input unit 4 to select a desired pattern from the patterns displayed on the display unit 5. The embroidery data selection unit 6 outputs the embroidery data of the pattern selected by the user to the temporary storage unit 9.
The temporary storage unit 9 stores the embroidery data selected by the embroidery data selection unit 6 as selected embroidery data. The temporary storage unit 9 is a so-called Random Access Memory (RAM), and a so-called volatile Memory or the like can be used.
The CRC data conversion unit 10 is a conversion unit that converts the selected embroidery data stored in the temporary storage unit 9 into CRC codes. The conversion into CRC code is performed by outputting a bit string (bit string) of the selected embroidery data as, for example, a 16-bit integer value. The CRC code must generate the same CRC code from the same selected embroidery data. Therefore, if even one byte (byte) of data is different between two selection embroidery data, a completely different code is generated as a CRC code. The CRC code converted by the CRC data conversion unit 10 is stored in the temporary storage unit 9 as CRC data corresponding to the selected embroidery data.
The status information creating unit 11 creates status data including the CRC data stored in the temporary storage unit 9 and the number of needles to be sewn by the sewing machine 2 with respect to the current embroidery pattern. The status data includes selected embroidery data and needle number data. The status data is data of about the size of a cross. The status information creating section 11 includes a CRC data acquiring section 12 and a pin number data acquiring section 13.
The CRC data acquisition unit 12 acquires CRC data stored in the temporary storage unit 9. The needle count data acquiring unit 13 is connected to the needle count counting unit 14, and acquires the number of needles counted by the needle count counting unit 14 as needle count data. The needle count counter 14 counts the number of needles to be sewn from the time when the sewing machine 2 starts embroidering to the time when the needle count data is acquired. The needle count counter 14 is connected to a motor (motor) that moves the sewing needle up and down, and counts the number of sewing needles based on the rotation of the motor.
The command receiving unit 15 is a receiving unit that receives a command transmitted from the embroidery status confirmation apparatus 3. The command transmitted from the embroidery state checking device 3 includes a state request signal and an embroidery data request signal. The command receiving unit 15 is kept on standby in a state where it can receive a command while the sewing machine 2 is operating.
The command determination unit 16 determines which of the "embroidery data request signal" and the "status data request signal" the command received by the command receiving unit 15 is. If the "embroidery data request signal" is received, a transmission command of "embroidery data" is transmitted to the TCP transmitter 17. If the "status data request signal" is received, a transmission command of "status data" is transmitted to the UDP transmission unit 18.
The TCP transmitting unit 17 is a transmitting unit that transmits TCP to the TCP receiving unit 29 of the embroidery status checking device 3 described below via the wireless network N. The TCP transmitting unit 17 reads the "selected embroidery data" stored in the temporary storage unit 9 based on the transmission command of the "embroidery data" from the command determining unit 16, and transmits the data by TCP communication. The TCP transmission is a communication protocol in which a connection (connection) is established before communication is performed, and transmission is performed after terminals performing communication make a virtual communication line with each other. TCP transmission is characterized by: and re-sending processing is carried out in the protocol to ensure that the sent data is delivered in a certain order and the sent data is delivered in sequence. Therefore, the reliability of transmission is high.
The UDP transmitter 18 transmits UDP to the UDP receiver 31 of the embroidery status checking device 3, which will be described later, via the wireless network N. The UDP transmitter 18 reads the "state data" created by the state information creation unit 11 based on the transmission command of the "state data" from the command determination unit 16, and transmits the "state data" by UDP communication. The UDP transmission is a very simple protocol, and is transmitted only once without retransmission, and does not guarantee that the transmitted data is delivered to the object. This UDP transmission is a communication protocol used when it is intended to increase the transmission rate, although there is a possibility that data is lost in the middle of the transmission. The UDP transmission is useful when data is to be continuously transmitted in real time.
[1-3. embroidery condition confirmation apparatus ]
The embroidery state confirmation means 3 transmits a command of "embroidery data request signal" or "status data request signal" to the sewing machine 2. In addition, the "embroidery data" and the "status data" transmitted from the sewing machine 2 are received in response to these commands. The embroidery status confirmation apparatus 3 draws the embroidery state in the sewing machine 2 on the display unit 35 based on the reception result of the data. As the embroidery state checking device 3, a general-purpose personal Digital assistant pda (personal Digital assistant) can be used. As shown in fig. 3, the embroidery condition checking device 3 includes a monitoring execution determination unit 20, a CRC data clear (clear) unit 21, a temporary storage unit 22, a command request unit 23, a CRC data comparison unit 26, a status information confirmation unit 27, a command transmission unit 28, a TCP reception unit 29, a CRC data conversion unit 30, a UDP reception unit 31, a drawing unit 34, and a display unit 35. The selected embroidery data and the CRC data are stored in the temporary storage unit 22.
The monitoring implementation judging unit 20 judges the start of monitoring the embroidery status of the sewing machine 2 in the embroidery status confirmation apparatus 3. The start of monitoring is determined when the power of the embroidery condition checking device 3 is turned ON (ON), when an application program for monitoring in the embroidery condition checking device 3 is started, or when a "synchronization" button (button) in the application program for monitoring is pressed.
If the start of monitoring is determined by the monitoring execution determination unit 20, the CRC data removal unit 21 deletes the CRC data stored in the temporary storage unit 22.
The command requesting unit 23 outputs a signal for requesting embroidery data or status data to the sewing machine 2. The request for instructions can be made at any interval. The shorter the interval of the instruction request, the smoother the embroidery condition of the sewing machine 2 displayed by the embroidery condition confirmation means 3. For example, the requests for instructions can be made at 0.5 second intervals. The command requesting unit 23 includes a status data requesting unit 24 and an embroidery data requesting unit 25.
The status data requesting unit 24 requests "status data" in the following cases (1) and (2).
(1) The monitoring implementation determination unit 20 determines that monitoring is started.
(2) When the following comparison result, that is, the comparison result that the CRC data stored in the temporary storage section 22 is the same as the CRC data confirmed by the status information confirming section 27, is input to the command requesting section 23 from the CRC data comparing section 26 described below.
When the comparison result of the next step, that is, the comparison result of the CRC data stored in the temporary storage unit 22 being different from the CRC data confirmed by the status information confirming unit 27, is input from the CRC data comparing unit 26 to the command requesting unit 23, the embroidery data requesting unit 25 requests "embroidery data".
The instruction transmitting portion 28 transmits a signal of "embroidery data request" or "status information request" from the instruction requesting portion 23 to the sewing machine 2. When a command is requested from the command requesting unit 23, the command transmitting unit 28 transmits a command.
The TCP receiving unit 29 receives the "selected embroidery data" transmitted by the TCP transmitting unit 17 of the sewing machine 2 by TCP communication. The "selected embroidery data" is stored in the temporary storage unit 22 of the embroidery status checking device 3.
The CRC data conversion unit 30 is a conversion unit for converting the selected embroidery data stored in the temporary storage unit 22 into CRC codes, as in the CRC data conversion unit 10 of the sewing machine 2. The CRC code converted by the CRC data conversion unit 30 is stored in the temporary storage unit 22 as CRC data corresponding to the selected embroidery data. The UDP receiving unit 31 receives the "state data" transmitted by the UDP transmitting unit 18 of the sewing machine 2 by UDP communication.
The status information confirmation unit 27 includes: a CRC data checking section 32 and a pin number data checking section 33, wherein the CRC data checking section 32 decodes the "status data" received by the UDP receiving section 31, extracts the "CRC data" included in the "status data", and checks the "CRC data"; the needle count data checking unit 33 checks the "needle count data" by extracting the "needle count data".
The CRC data comparison section 26 compares the CRC data stored in the temporary storage section 22 with the CRC data confirmed by the status information confirmation section 27. The comparison result is output to the command requesting unit 23.
The drawing unit 34 draws the image data displayed on the display unit 35 based on the "selected embroidery data" stored in the temporary storage unit 22 and the "needle count data" confirmed by the needle count data confirmation unit 33 of the state information confirmation unit 27. The drawing unit 34 includes an embroidery data drawing unit 36, a drawing position determining unit 37, and a drawing speed determining unit 38.
The embroidery data drawing unit 36 draws based on the information of the "selected embroidery data" and the "needle count data". Fig. 4 is a diagram showing an example of image data displayed on the display unit 35. The embroidery data drawing unit 36 performs the following drawing based on the information included in the "selected embroidery data".
(1) The drawing is completed based on the information of the embroidery pattern.
(2) The number of pins required until completion is depicted based on the information of the number of pins required to complete the pattern.
(3) The size of the embroidery to be completed is depicted based on the size information of the pattern.
(4) The number of colors of the line used is drawn based on the color information used.
(5) Based on the information of the time point for replacing the thread, a thread to be used until the thread is completed and a column (bar) of the number of needles to be sewn with the thread are drawn.
The embroidery data drawing unit 36 performs the following drawing based on the information included in the "needle count data".
(6) A drawing of the current number of needles since the start of embroidery is performed.
The drawing position decision unit 37 draws which part of the embroidery data selected by the sewing machine 2 is being embroidered based on the current "needle count data" and "selected embroidery data".
The drawing speed determination unit 38 determines the drawing speed based on the difference of the "needle count data". The drawing speed determination unit 38 stores the "needle count data" at the previous reception in advance, and calculates a difference from the "needle count data" newly received. For example, since the drawing interval for each stitch in the embroidery condition checking device 3 is changed according to the number of rotations of the sewing machine 2, it can be determined from the number of stitches increased in a certain period of time. For example, in the case where the number of needles is acquired at 0.5 second intervals, if the "number of needles data" is increased by 5 needles from the time of the last acquisition, drawing is performed at 0.1 second per needle. This corresponds to 600 revolutions/minute of the motor that moves the sewing needle of the sewing machine 2 up and down. In addition, if 4 pins are added each time, the delineation is performed at 0.125 second intervals per pin (equivalent to 450 rpm). By determining the drawing interval time in accordance with the increased number of needles, the drawing update on the embroidery condition checking device 3 can be smoothly performed.
[1-4. Effect ]
The operation of the embroidery situation confirmation system 1 according to the present embodiment configured as described above will be described in detail with reference to fig. 5 to 7. The system connects a sewing machine 2 and an embroidery condition confirmation apparatus 3 by a wireless network N. Thereby, the sewing progress state of the sewing machine is monitored in real time by the display unit 35 of the embroidery state confirmation apparatus 3 at a place distant from the sewing machine 2. The operation of the sewing machine 2 constituting the embroidery condition checking system 1 will be described separately from the embroidery condition checking device 3.
(1) About the movement of the sewing machine side
Fig. 5 is a flowchart of the embroidering by the sewing machine 2. When embroidering with the sewing machine 2, the user selects a desired embroidery pattern (step 101). The desired embroidery pattern is a candidate pattern displayed on the display unit 5 of the sewing machine 2 selected via the input unit 4.
The embroidery data corresponding to the selected embroidery pattern is stored in the temporary storage unit 9 as selected embroidery data. The CRC data conversion unit 10 calculates the CRC code of the selected embroidery data and stores the CRC code in the temporary storage unit 9 as CRC data (step 102).
Thereafter, after setting the cloth and the designated thread in the sewing machine 2, the user presses an embroidery start button provided in the sewing machine 2 (yes in step 103). Thereby, the sewing machine 2 starts embroidery based on the selected embroidery data.
If embroidery is started, the number of needles since the start of embroidery is counted by the needle count counting section 14 while the embroidery is being executed. The number of pins is the number of pins that is updated in the memory of the number of pins counting unit 14 each time the number of pins is counted by the number of pins counting unit 14 (step 104). The counting of the number of needles continues until the embroidery is finished.
The sewing machine 2 ends the embroidery if the embroidery is performed until the selected embroidery data is completed. Thereafter, when another embroidery is performed (no in step 105), the user selects the embroidery pattern again, and the sewing machine 2 performs the embroidery of the embroidery pattern (steps 101 to 105). On the other hand, when the other embroidery is not performed, the sewing machine 2 ends the embroidery operation (yes at step 105).
(2) Concerning interrupt handling in the sewing machine 2
Fig. 6 is a flowchart showing a process when the sewing machine 2 receives a command from the embroidery condition checking device 3.
In the flowchart shown in fig. 5, after passing through step 102 of calculating a CRC code of the selected embroidery data and storing it as CRC data, the sewing machine 2 communicates with the embroidery condition confirmation apparatus 3 via the wireless network N by interrupt processing. At this time, the command receiving unit 15 of the sewing machine 2 receives the command transmitted from the embroidery condition checking device 3 (step 111).
When the command receiving unit 15 receives the command, the command judging unit 16 judges whether the command is a command of "embroidery data request" or a command of "status information request" (step 112).
When the command is a "status data request" command (0 in step 112), the UDP transmitter 18 transmits the status data created by the status information creation unit 11 to the UDP receiver 31 of the embroidery status confirmation device 3 (step 113). The status data includes CRC data obtained by converting the selection pattern data in the current embroidery into CRC codes, and the current needle number.
On the other hand, when the instruction is an "embroidery data request" (1 at step 112), the TCP transmitting unit 17 transmits the selected embroidery data currently being embroidered, which is stored in the temporary storage unit 9, to the TCP receiving unit 29 of the embroidery status checking device 3 as embroidery data (step 114).
The sewing machine 2 receives the interruption process until the embroidery is finished or the power is turned OFF (OFF). When a new interrupt process is accepted, the following steps are repeated from the step of receiving the command (step 111).
(3) Regarding the operation of the embroidery status confirmation apparatus 3 side
Fig. 7 is a flowchart when the embroidery status confirmation is performed by the embroidery status confirmation device 3. When the user confirms the embroidery condition of the sewing machine 2 in the embroidery condition confirmation apparatus 3, the embroidery condition confirmation application installed in the embroidery condition confirmation apparatus 3 is started.
When the monitoring process is started, the CRC data removal section 21 deletes the CRC data stored in the temporary storage section 22 (step 131).
Thereafter, status data related to the current embroidery pattern is requested to the sewing machine 2 (step 132). The request for the state data is output from the state data requesting section 24 of the command requesting section 23 and is output to the sewing machine 2 via the command transmitting section 28.
After the status data request is transmitted from the command transmitting unit 28, a response of status data based on the status data request from the sewing machine 2 is waited for (step 133). When the UDP reception unit 31 receives the status data from the sewing machine 2, the CRC data comparison unit 26 compares the CRC data included in the received status data with the CRC data stored in the temporary storage unit 22 of the embroidery condition confirmation apparatus 3 (step 134).
When the CRC data received from the sewing machine 2 does not match the CRC data stored in the temporary storage section 22 (0 in step 134), the state data requesting section 25 of the instruction requesting section 23 requests the sewing machine 2 for the pattern data currently in embroidery (step 135). The CRC data of the status data received from the sewing machine 2 does not match the CRC data stored in the temporary storage unit 22, and examples thereof include a case where the CRC data of the temporary storage unit 22 is deleted at the start of monitoring, and a case where the change of the embroidery data is selected on the side of the sewing machine 2.
When the embroidery data request is transmitted from the command transmitting unit 28, a response of the embroidery data based on the embroidery data request from the sewing machine 2 is waited for (step 136). The TCP receiving unit 29 receives the embroidery data from the sewing machine 2 and stores the embroidery data in the temporary storage unit 22. The CRC data conversion section 30 calculates the CRC code of the stored selected embroidery data and stores the CRC code in the temporary storage section 22 as CRC data (step 137).
On the other hand, when the CRC data of the status data from the sewing machine 2 matches the CRC data stored in the temporary storage unit 22 (step 1 of step 134), drawing is performed based on the needle count data of the status data received from the sewing machine 2 and the selected embroidery data stored in the temporary storage unit 22. The drawing speed at the time of drawing is determined based on the difference between the needle count data of the state data received from the sewing machine 2 and the needle count of the state data received last time (step 138). In the present embodiment, since the embroidery situation confirmation apparatus 3 inquires the current number of stitches of the sewing machine at 0.5 second intervals, if the difference between the previous number of stitches and the current number of stitches is five stitches, one stitch is drawn at intervals of 0.1 second. Then, the drawing unit 34 performs drawing at the drawing speed (step 139).
The above processing is continued until the monitoring processing ends (no at step 140). In the present embodiment, step 132, step 133, step 134, step 138, step 139, and step 140 are repeatedly performed at 0.5 second intervals. This makes it possible to display a graphic (graphic) of a stitch synchronized with the actual sewing needle of the sewing machine on the embroidery condition checking device 3.
(4) Actions at the beginning of the monitoring process
Fig. 8 is a sequence diagram of the embroidery situation confirmation system 1 when the embroidery situation confirmation apparatus 3 confirms the embroidery situation of the sewing machine 2.
First, when embroidering is performed in the sewing machine 2, the user selects a pattern. When the user selects the pattern data "flower 001", the pattern data "flower 001" is stored as the selected pattern data in the temporary storage unit 9. At the same time, the CRC code "D1" calculated from the pattern data "flower 001" is stored as CRC data in the temporary storage section 9.
On the other hand, in order to perform the monitoring process by the embroidery situation confirmation apparatus 3, an application program for embroidery situation confirmation built in the embroidery situation confirmation apparatus 3 is started. Thereby, the monitoring process is started. When the monitoring process is started, the CRC data stored in the temporary storage unit 22 of the embroidery condition checking device 3 is initialized (the CRC data is 0).
Thereafter, the embroidery situation confirmation apparatus 3 transmits a command requesting the state data to the sewing machine 2. The sewing machine 2 receives the instruction and returns the current status data. The status data includes CRC data "D1".
The embroidery state checking device 3 receives the state data including the CRC data and compares the state data with the CRC data stored in its own storage unit. As a result, the CRC data on the sewing machine side is "D1", whereas the CRC data on the embroidery condition checking device 3 side is "0", and thus it is determined as "inconsistent".
The embroidery condition checking device 3 transmits an instruction for requesting selection of embroidery data to the sewing machine 2 based on the comparison result of the CRC data of "inconsistency". The sewing machine 2 receives the instruction and returns the currently selected embroidery data. The selected embroidery data is "flower 001".
The embroidery status checking device 3 receives the selected embroidery data and stores the data in the temporary storage unit. Meanwhile, a CRC code is calculated from the pattern data "flower 001". When communication is performed normally, the CRC code is D1, and "D1" is stored as CRC data.
The embroidery state checking device 3 sends a command requesting the state data and returns the state data from the sewing machine 2 again. Then, the embroidery state confirmation apparatus 3 compares the CRC data of the state data from the sewing machine 2 with the CRC data "D1" stored in its own storage unit. As a result, the CRC data on the sewing machine side is "D1", whereas the CRC data on the embroidery condition checking device 3 side is "D1", and thus it is determined to be "identical".
If it is determined as "match", drawing is performed in the embroidery situation confirmation apparatus 3 based on the received selection image data "flower 001" and the number of needles included in the status data.
(5) About the action when selecting patterns on the sewing machine side
Fig. 9 is a sequence diagram of the embroidery situation confirmation system 1 when the embroidery situation confirmation of the sewing machine 2 is performed by the embroidery situation confirmation apparatus 3 when the selection pattern data "flower 001" is changed to "sea 020" in the sewing machine 2.
In the sewing machine 2, "flower 001" and CRC data "D1" thereof are stored as selection pattern data in the sewing machine 2 when embroidering based on the pattern data "flower 001". On the other hand, the embroidery state checking device 3 also stores "flower 001" and CRC data "D1" as the selection pattern data. The request command of the state data and the reply of the state data based on the request command of the state data are performed between the sewing machine 2 and the embroidery condition confirmation device 3. In the embroidery situation checking device 3, the display unit 35 draws the "number of stitches" based on the selection pattern data "flower 001" and the received state data.
In this state, when the selection pattern data is changed from "flower 001" to "sea 020" in the sewing machine 2, the pattern data "sea 020" is stored as the selection pattern data in the sewing machine 2. Meanwhile, a CRC code "D2" calculated from the pattern data "sea 020" is stored as CRC data.
When receiving the command requesting the status data from the embroidery status confirmation device 3, the sewing machine 2 returns status data including CRC data "D2".
The embroidery state checking device 3 receives the state data including the CRC data and compares the state data with the CRC data stored in its own storage unit. As a result, the CRC data on the side of the sewing machine 2 is "D2", whereas the CRC data on the side of the embroidery state checking device 3 is "D1", and thus it is determined to be "inconsistent".
The embroidery condition checking device 3 transmits an instruction for requesting selection of embroidery data to the sewing machine 2 based on the comparison result of the CRC data of "inconsistency". The sewing machine 2 receives the instruction and returns the currently selected embroidery data. The selected embroidery data is "sea 020".
The embroidery status checking device 3 receives the selected embroidery data and stores the data in the temporary storage unit 22. Meanwhile, a CRC code is calculated from the pattern data "sea 020". When communication is normally performed, the CRC code D2, "D2" is stored as CRC data.
Thereafter, the embroidery state checking device 3 transmits a command requesting the state data and returns the state data from the sewing machine 2 again. Then, the embroidery condition checking device 3 compares the CRC data of the status data from the sewing machine 2 with the CRC data stored in its own storage unit. As a result, the CRC data on the side of the sewing machine 2 is "D2", whereas the CRC data on the side of the embroidery state checking device 3 is "D2", and thus it is determined to be "identical".
If the image data "match" is determined, the embroidery situation checking device 3 performs drawing based on the received selected image data "sea 020" and the number of needles included in the state data.
[1-5. Effect ]
The embroidery state checking system 1 according to the present embodiment as described above can exhibit the following effects.
(1) By performing communication between the sewing machine 2 and the embroidery status confirmation apparatus 3 via the wireless network N, the embroidery status of the sewing machine 2 can be confirmed by the embroidery status confirmation apparatus 3. Is characterized in that: not only the monitoring is performed near the sewing machine 2, but also the monitoring is resumed immediately when the embroidery status checking device 3 is brought out of the communication range and the state is changed to a state capable of communicating again, thereby accurately resuming stitch (stich) drawing.
Both the TCP protocol and the UDP protocol are used in communication via the wireless network N. The TCP protocol requires a relatively large data transfer (several hundred kilobytes or so), but can transmit data accurately because it transmits data while confirming whether or not the data is delivered to an object. The embroidery data is transmitted through a TCP protocol in the transmission process.
On the other hand, the UDP protocol can communicate with relatively small data transfers (on the order of tens of bytes). Since transmission of about several tens of bytes is performed at intervals of several hundred milliseconds during monitoring, the amount of data to be communicated can be controlled to be very small. In addition, since the UDP protocol is used for monitoring, if data cannot be received, the packet (packet) is discarded and the next reception is waited. That is, even if the communication is interrupted, the drawing process is restarted from the time when the communication is accurately received, without stopping the communication particularly by detecting an error, until the communication is accurately received. That is, even if communication is temporarily interrupted, it is possible to easily recover from the time when accurate reception is possible.
(2) The selected embroidery data is provided in both the temporary storage unit 9 of the sewing machine 2 and the temporary storage unit 22 of the embroidery situation checking device 3. In addition, the selected embroidery data stored in the two storage units 9 and 22 are not directly compared, but compared with each other by the CRC code calculated from the selected embroidery data. Therefore, even if the user changes the next pattern during a long interruption of communication, the two patterns hold a unique code (for example, CRC code) for the pattern, and if the embroidery condition checking device 3 is notified of the code from the sewing machine 2, the codes do not match with each other, and therefore the embroidery condition checking device 3 can recognize that the pattern has been changed. When recognizing the change of the pattern, the embroidery condition confirmation apparatus 3 requests data of the pattern currently being sewn by the sewing machine 2 and receives the data from the sewing machine 2. The data communication at this time is carried out by using the TCP protocol, and the embroidery data is delivered without error. The TCP protocol is not real-time, but can accurately transmit data to the embroidery condition checking device 3, and therefore, the TCP protocol is replaced with the same data as the sewing machine 2, and the same pattern is displayed on the embroidery condition checking device 3.
(3) During the stitch formation by the sewing machine 2, the stitch is graphically depicted on the embroidery condition confirmation apparatus 3 located at a place distant from the sewing machine 2. At this time, the actual sewing is synchronized with the drawing of the pattern, and the stitch is drawn quickly when the sewing is performed at a high speed, and the stitch is drawn slowly when the sewing is performed at a low speed. Therefore, the user can easily grasp what embroidery is being performed even at a place away from the sewing machine 2.
(4) Since communication is performed using radio waves, the communication environment may be deteriorated due to radio wave intensity, a distance between communications, and obstacles such as walls. Particularly, when the embroidery situation confirmation apparatus 3 is carried around, the communication may be temporarily interrupted. If the location is changed again, or the orientation of the embroidery condition confirmation apparatus 3 is changed, the communication can be restarted. During the communication interruption period, the drawing by the embroidery condition checking device 3 is also stopped, but when the communication is resumed, the sewing machine 2 and the embroidery condition checking device 3 are synchronized by drawing the stitch to be actually sewn.
[2 ] Another embodiment ]
As described above, the embodiments of the present invention have been described, but various omissions, substitutions, and changes can be made without departing from the spirit of the invention. The embodiment or the modifications of the embodiment are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
In the first embodiment, the CRC code is calculated from the selected embroidery data stored in the temporary storage unit of the sewing machine 2 and the temporary storage unit of the embroidery condition checking device 3, and is used as the CRC data. However, the pattern data may be converted to data other than CRC data as long as the data is a code unique to the pattern data and has a smaller capacity than the pattern data. For example, as shown in fig. 10, code conversion units 41 for performing code conversion in the same manner are provided in the temporary storage units of the sewing machine 2 and the embroidery situation confirmation apparatus 3, respectively. The code conversion unit 41 converts the pattern data into a code having a small capacity and performing unique code conversion. The converted unique codes are stored in the temporary storage units, respectively.
In the case of converting the embroidery data into a unique code, the embroidery data may be divided into various standards (standards) and a part of the embroidery data may be converted into a unique code, in addition to converting the whole embroidery data.
In the first embodiment, the "selected embroidery data" is transmitted from the sewing machine 2 to the embroidery condition confirmation device 3 by the communication using the TCP protocol, and the "state data" is transmitted from the sewing machine 2 to the embroidery condition confirmation device 3 by the communication using the UDP protocol, but the combination of the communication protocols is not limited to this combination. That is, as long as the transmission protocol is a transmission protocol capable of accurately transmitting data to a transmission destination, a communication protocol other than the TCP protocol may be used as the "selection of embroidery data". In addition, as the "state data", a communication protocol other than the UDP protocol may be used as long as it is a transmission protocol capable of transmitting data to a transmission destination in a short time.
In addition, the embroidery status confirmation apparatus 3 can display not only the embroidery status in the sewing machine 2 but also an event (event) such as a thread replacement as shown in fig. 11. The other event may be an event such as stopping the sewing machine due to a thread being wound or broken.
